Mitsubishi M80 Linear Servo Motor 200V LM-FS20-☐-1WWO

LM-FP2F-18M-1WW0 (often typed as “1WWO”) is a Mitsubishi Electric LM-F series linear servo motor primary side (coil assembly). It is the 1800 N continuous thrust class model in the LM-FP2 family and is used in high-speed CNC and precision automation systems.

LM-FS20-☐-1WW0 (often typed as “1WWO”) is the Mitsubishi Electric LM-F series secondary side (magnet track assembly) used with LM-FP2 linear servo motor primary coils.

It is the fixed permanent-magnet rail portion of the LM-F linear motor system. The “☐” represents different available magnet track lengths.

Available LM-FS20 variants

Mitsubishi documentation confirms these are the available secondary-side lengths for the LM-FS20 series.

⚙️ What it is

This component is:

• the stationary magnetic rail
• used together with LM-FP2 coil units
• part of a core-type linear servo motor system

It works with:

• LM-FP2A-03M-1WW0
• LM-FP2B-06M-1WW0
• LM-FP2D-12M-1WW0
• LM-FP2F-18M-1WW0

depending on required thrust and amplifier sizing.

📐 Mechanical details (LM-FS20 series)

Detailed Mitsubishi dimension tables show:

• 384 mm version → 4×2 mounting pattern
• 480 mm version → 5×2 mounting pattern
• 576 mm version → 6×2 mounting pattern

⚠️ Important handling notes

• Delivered fully magnetized
• Very strong magnetic attraction force
• Requires careful installation near steel tools/components
• IP00 → must be installed inside machine enclosure
• Proper air gap alignment with primary coil is critical

Mitsubishi manuals specifically warn about handling magnet assemblies carefully to avoid injury or damage.

🧠 Simple explanation

LM-FS20-☐-1WW0 is the magnet rail of a Mitsubishi linear motor system.

It does not move by itself — the moving coil unit (LM-FP2 series) travels along this magnetic track to create:

• high-speed linear motion
• zero backlash
• very precise positioning
